Abstract

This article analyses how regional employment growth in Germany is affected by related variety, unrelated variety and the functions a region performs in the production process. Following the related variety literature, we argue that regions benefit from the existence of related activities that facilitate economic development. However, we argue that the sole reliance of related variety on standard industrial classifications remains debatable. Hence, we offer estimations for establishing that conceptual progress can indeed be made when a focus for analysis goes beyond solely considering industries. We develop an industry-function based approach of related and unrelated variety. Our findings suggest that related variety only in combination with a high functional specialization
of the region facilitates regional growth in Germany. Additionally, also unrelated
variety per se fails to wield influences affecting development of regions. It is rather unrelated, but functionally proximate variety in the groups “White Collar” and “Blue Collar Workers” positively affects regional employment growth.

Determinants of the Efficiency of Regional Innovation Systems

Michael Fritsch, Viktor Slavtchev

Regional Studies,
No. 7,
2011

Abstract

Determinants of the efficiency of regional innovation systems, Regional Studies. This paper analyses differences in the efficiency of regional innovation systems. Alternative measures for the efficiency of regional innovation systems based on the concept of a knowledge production function are discussed. The empirical findings suggest that spillovers from within the private sector as well as from universities and other public research institutions have a positive effect on the efficiency of private sector research and development. It is particularly the intensity of interactions between private and public sector research and development that increases the efficiency. It is found that regions dominated by large establishments tend to be less efficient than regions with a lower average establishment size.

Metropolitan Area „Central Germany“: How Strong are the Commuting Flows between the Cities?

Albrecht Kauffmann

Wirtschaft im Wandel,
No. 2,
2011

Abstract

The metropolitan area „Central Germany“ is an institutional agreement on co-operation between the bigger cities of the German Länder Saxonia, Saxony-Anhalt and Thuringia. It is one of now eleven “European Metropolitan Areas” acknowledged by the Conference of German Ministers for Spatial Planning. In the face of the multitude of cities and the large distances between the cities at the fringe and the geographical centre of the metropolitan area “Central Germany” should be regarded as a very special case. Another peculiarity is that the hinterland of the metropolitan area has not yet been delineated. The paper analyses the networking interrelations between the eleven cities on the basis of commuting flows. Additionally, proposals for the delimitation of this metropolitan area as a polycentric functional urban area are suggested for the first time. The investigation yields that network connectivity between the cities that have shaped the former metropolitan area “Halle/Leipzig-Saxonian Triangle”, as well as the Thuringian cities is much more intensive than the commuting flows between these subareas that are well connected from history. As a functional area, the metropolitan area “Central Germany” would have a very large hinterland, but its population density would be rather small, and it would interact only with the nearest regional centres. One can conclude that the preconditions for successful cooperation are better for adjacent cities which collaboration has already a long tradition.

Identifying Industrial Clusters from a Multidimensional Perspective: Methodical Aspects with an Application to Germany

Matthias Brachert, Mirko Titze, Alexander Kubis

Papers in Regional Science,
No. 2,
2011

Abstract

If regional development agencies assume the cluster concept to be an adequate framework to promote regional growth and
competitiveness, it is necessary to identify industrial clusters in a comprehensive manner. Previous studies used a diversity of methods to identify the predominant concentrations of economic activity in one industrial sector in a region. This paper is based on a multidimensional approach developed by Titze et al. With the help of the combination of concentration measures and input–output methods they were able to identify horizontal and vertical dimensions of industrial clusters. This paper aims to reﬁne this approach by using a superior measure of spatial concentration and by integrating information about spatial interdependence of industrial cluster structures to contribute to a more adequate framework for industrial cluster identiﬁcation.

Abstract

Knowledge of factors that determine the transition from nascent entrepreneurship into real entrepreneurship is of major importance for policies aiming to effectively stimulate start-ups. Whereas scholars concentrated on person-specific factors to explain transition probabilities, environmental characteristics have been fairly neglected. Given that entrepreneurship is a strongly localized phenomenon, this paper argues that regional entrepreneurial opportunities are a driving force behind the transition from nascent entrepreneurship to new venture creation. Based on unique data on 103 nascent entrepreneurs in the German biotechnology industry, we empirically assess the importance of regional entrepreneurial opportunities on transition probabilities. Further, we introduce a new
approach to measure nascent entrepreneurship by capturing individuals that actively participate in start-up competitions and have won at least one competition. Controlling for technology and individual characteristics, we find strong support for our hypotheses relating to the significant impact of general regional opportunities, specific regional opportunities and the entrepreneurial environment for the probability of transition from award-winning nascent entrepreneurs to real start-ups.

Transport Costs and the Size Distribution of a Linearly Arranged System of Cities

Albrecht Kauffmann

IWH Discussion Papers,
No. 26,
2010

Abstract

The question regarding the effects of changing transports costs on the size distribution of cities is an important topic of systems of cities research. The so-called New Economic Geography has already given some answers to this question. One central assumption in this kind of model is a very particular, simplified spatial structure. This contribution investigates the consequences of changing transport costs for a system of cities that are located equidistantly on a straight line. In the case of rising transport costs, the main outcome of this model is worker concentration in the central large cities, while the peripheral regions lose residents.

The Russian System of Cities from the Perspective of New Economic Geography

Albrecht Kauffmann

Potsdamer Schriften zur Raumwirtschaft, Bd. 2,
2010

Abstract

The rise in energy prices may result in long-lasting rise in costs of freight transports. Which effects do rising freight transport costs have for the development of urban systems? Such rise of transport costs in real terms has happened in Russia after price liberalisation in 1992. At the same time, the Russian official demographic statistics provides data that can be used to test hypotheses concerning the development of urban systems affected by rising transport costs. In the present study, these data are comprehensively evaluated. The theoretical background is provided by modelling of a linear shaped urban system in the framework of New Economic Geography. By means of this tool, analysis can be applied to spacious urban systems with large transport distances. For the first time, the underlying theoretical approach is explained in detail. The empirical results provide evidence for the outcomes of the theoretical model: In spacious countries or regions, respectively, whose urban systems are drawn-out on long lines, rising costs of freight transport are conducive to tendencies of concentration of population in large cities in the centre of the system, while peripheral regions are increasingly disconnected.

How Does Industry Specialization Affect the Efficiency of Regional Innovation Systems?

Michael Fritsch, Viktor Slavtchev

The Annals of Regional Science,
No. 1,
2010

Abstract

This study analyzes the relationship between the specialization of a region in certain industries and the efficiency of the region in generating new knowledge. The efficiency measure is constructed by relating regional R&D input and output. An inversely u-shaped relationship is found between regional specialization and R&D efficiency, indicating the presence of externalities of both Marshall and Jacobs’ type. Further factors influencing efficiency are externalities resulting from high R&D intensity of the local private sector as well as knowledge from local public research institutions. The impact of both the specialization and the additional factors is, however, different for regions at different efficiency levels.

The Identification of Industrial Clusters – Methodical Aspects in a Multidimensional Framework for Cluster Identification

Mirko Titze, Matthias Brachert, Alexander Kubis

IWH Discussion Papers,
No. 14,
2010

Abstract

We use a combination of measures of spatial concentration, qualitative input-output analysis and innovation interaction matrices to identify the horizontal and vertical dimension of industrial clusters in Saxony in 2005. We describe the spatial allocation of the industrial clusters and show possibilities of vertical interaction of clusters based on intermediate goods flows. With the help of region and sector-specific knowledge interaction matrices we are able to show that a sole focus on intermediate goods flows limits the identification of innovative actors in industrial clusters, as knowledge flows and intermediate goods flows do not show any major overlaps.

Knowledge Spillovers as a Central Element in Theories about Knowledge-Based Regional Development: Advancement in Theory and Obstacles for Empirical Research

Abstract

As scientists and policymakers tend to interpret changes in the economy as a trend towards an increasingly knowledge-based economy, their recommendations and strategies for regional economic development frequently contain elements how to intensify the knowledge flows in the region concerned. Knowledge flows come into existence from intentional action, but also in an unintended way as externalities or knowledge spillovers. This paper reviews the ways regional and urban economics has dealt with the concept of knowledge spillovers. Knowledge spillovers are defined within a conceptual framework that points out different uses of knowledge in economics. The concept’s operationalisations in diverse empirical studies are systematised and discussed. After a critical review of the current state of research, policy strategies aiming to intensify knowledge spillovers are classified. The paper concludes with an outlook on promising new approaches to research knowledge spillovers and on the elaboration of more efficient policy strategies.
